Guyed Towers are limited in Height due to the nature of Antenna and Ice loads versus the Cantilever Nature Of Wind against them, offset by the Downward force of all Downguy tensioned as specified, terminated to a properly embedded Anchor, the weight/size of the Foundation and the cohesive of the soil to prevent skid/pullout and all together to counter a Structural Failure or Tower tip-over moment, as well as the strength of the tower members to withstand these Forces against them. ROHN Tower Kits are designed based on assumptions made regarding Windspeed, EPA (Antenna Load), Ice Load, Transmission Cable Loads, Height, Standard Soil Conditions, Surrounding Environment and Duty (Exposure Categories).
The Pre-packaged Kits contain the parts called for based on this Stock Design. The Stock Design of these Kits does not account for the Variations of Historic Windspeed, Number of Antenna(e) Loading at Specific Height(s), Soil Engineering recommendations, Adjacent Structures, Communications Purpose, or Geo-Political Rules, Laws and Codes That will be Applicable to Your Project.
It is Recommended that you take the time to engage an local Engineer that has the expertise and available Information necessary to evaluate the Stock design for Applicability, and/or Fill Out the Tower Quote Data Sheet Form found by clicking the Specification Tab above and send to 3 Star Inc./ROHN for a review.
*Per Rev G requirements, any structure greater than 10' foot requires a climber safety device.

Remember those older AM/FM Portable Radios with the antenna that you extended by pulling it out? Or the Radio Antennas on older cars that would pop- out, extend and retract when you turned on the radio? This Mast isn't an Antenna, but it extends and retracts by hand in similar fashion. Available in 20', 30', 40' and 50' heights. All ROHN telescoping masts are pre-galvanized and come assembled with hardware. Erection is made by simply connecting guys and brackets to the attached unique heavy duty rolled edge guy rings and clamps, extend each section one at a time (starting with the innermost section), insert the locking cotter pins, rotating the tubes to a locked position, and tightening the clamps. Repeat the process on each successive section until fully erect.
The unique ROHN Products design features interior tube flanging combined with a double crimped exterior tube to produce a stronger and more stable joint than most common masts. This design exclusive also prevents the sections from accidentally pulling apart and allows disassembly by pulling each section out through the lower end.
Each section extends deeper in to the lower tubes than most other designs, adding still further to the stability of the structure.
H Series
This heavy duty series uses 1-1/4" 16 gauge galvanized tubing for top section. All other sections are 18 gauge.
Assembly
1. Secure base and anchors (sold separately).
2. Attach lowered mast to base.
3. Secure guy lines to the lower Guy Ring and attach to anchors. Align the mast vertically by tightening the Guy Lines.
4. Secure upper Guy Ring using the appropriate Mast Clamp to desired location on the upper Tube (see note 8 on page 10).
5. Secure appropriate length guy lines to the upper Guy Ring and let them hang.
6. Raise the upper Tube and inset the cotter pin. Make sure that the cotter pin is inside the notch in the inside tube.
7. Secure the cotter pin and tighten the mast clamp.
8. Secure appropriate length guy lines to the next highest Guy Ring, and let them hang.
9. Raise the next smallest Tube and insert the cotter pin. Make sure that the cotter pin is inside the notch in the inside tube.
10. Secure the cotter pin and tighten the mast clamp.
11. Repeat steps 8-10 until all sections have been raised and are secured.
12. Attach all hanging Guy Lines to their respective anchor. Align the mast vertically by tightening the Guy Lines. Make sure to work your way up the mast while tightening.
